UNDERFRAME FOR DUMPING-CARS.

' Specification of Letters Patent.

Patented Ma er, 1913.

Original application filed March 5, 1916, Serial No. 547,569, Divided and this application filed May 29,

1911. Serial No. 630,188.

To all whom it mag concern Be it known that lVILLIAM P. BE'L'I'EN- nonr, deceased, late a citizen of the United States, residing at Bettendorf, in the county of Scott and State of Iowa, did invent certain new and useful Improvements in Under-frames for Dumping-Cars, ofwhich the following is a full, clear, and exact description.

This invention relates to the underframes of dumping cars, and particularly tofthat type of dumping cars, whose bodies are adapted to be lifted from their trucks, such as those set forth and claimed in a copending application for patent, filed by said WILLiAM P. Bn'rrnxnonr, on March 5, 1910, Serial No. 547,569, 8r ivhich this application is a division and which resulted in Patent No. 1,039,638, dated Sept. 24:, 1912.

The objects of this invention are to provide an economically constructed underframe for a dump-car body, so that the tilting of said body can be accomplished without alfecting the relation of thebody bolster to the truck-bolster.

It is also an object of this invention to construct an underframe that will lower the floor of a tilting dump-car so as to obtain as low a center of gravity as possible without striking the flange or rim of the wheels, which especially adapts the car for use in mines, subways and similar work These and other objects are accomplished by the means and in the manner hereinafter fully described and as more particularly pointed out in the claims, reference being had to the accompanying drawings forming a part hereof, in which,

Figure l is a top plan view of the underframe of one-half of a dump car embodying said invention. Fig. 2 is a bottom plan view of the same removed from the trucks, Fig. 3 is a transverse vertical .sectiontaken on dotted line 33, Fig. 1. Fig. 4 is a view similar to Fig. 3 showing thecar in its tilted position. Fig. 5 is an end view of said car illustrating the means for manipulating the jointed braces, and the hooks, for maintaining the car in its tilted position, or inits-horizontal position' Fig. 6 is a view similar to Fig. 3 showing the car converted to a rigid. body.

In drawings A, A, represent Z-bar consists of a fiat upper side-sills; B, B, center-sills, and C the endsills. The end-sills are, preferably, made of cast metal, and the central portion of its inner 'side extends in the horizontal plane of the floor of the car, inward toward the body-bolster, to a point about midway between the transverse plane of the pivot of the truck and thecnd of the car, and its rear edge portion is provided with adepressed seat w in which the lower flanges of the center-sills are seated and suitably secured so that their upper surfaces are in .the same-plane as the upper surface of said extension The body-bolster comprises two parts,

whichv may be the bolster proper and the cradle. The bolster consists, preferably, of a transverse cast metal beamextending from side-sill to side-sill ofthe car, the central part of .wh'ich is rectangular in cross section and tubular and the portions between this central part and its ends are channeled and the lower edges of the sidewalls of said channeled portions arefianged inward. The. top of this bolster proper plate, D, the upper surface of which is in the same horizontal plane as the upper surface of the upper flanges of the center-sills and side-sills, and the lower port-ion thereof has its vertical parallel side-walls (Z separated a distance less than the width of said top-plate, D, and .is bellied downward so that the depth thereof is greatest at its center of length and sothat the lower side thereof is curved to enable it to rock from one side to the other on its lower edges. The lower side edges of said bolster are provided with recesses E, which are, preferably, oppositely arranged in pairs in the same transverse plane, and so that each pair will be equal distances apart. The center of length of the upper portion of this bolster is provided with a suitable transverse depressed scat f of sufficientdimensions to permit the passage of the center-sills B, B, and which .is ofsuch depth that the upper surfaces of the upper flanges of said sills will be in the some horizontal plane as the upper surface of the bolster.

The ends of the bolster are seated upon the inturried lower flanges of the Z-bar side sills A, anda're uitablylsecured thereto by rivets or otherwise, and the floor G of the car, which consists, preferably, of a single sheet metal plate, extending from end to end and side to side. of, the car, is riveted to the center-sills, the side-sills and bolsters of the underframe.

The bolster rests upon and is seated in a cradle consisting of a transverse channeled trucks.

beam H, the bottom plate or web of which extends in a'straight horizontal plane from end to end, and is provided at the inner angles of the lower flanged edges of its sidewalls with protuberances that constitute teeth or cogs 9 that are adapted to be en gaged'by the recesses E in the lower edges of the bolster. It is preferable to arrange these cogs g and recesses E so that there will be one at the centers of length of the bolster and cradle in the longitudinal plane of the king-bolt of the truck, and an equal number between the same and each end of the bolster. Thus, when the floor of the car is in its normal horizontal position the central cogsand recesses will'be in engagement, and when the car is tilted the engagement of said cogs andrecesses will prevent the car-body.

from slipping upon said cradle H and thus injure their proper relation.

At its center of length the cradle. has a suitable male center-bearing 6 made integral with and depending from its under surfate that is adapted to engage a suitable female bearing 3 of any of the usual types of car- The means for tilting the body (if the car preferably comprise a toggle or jointed brace or strut consistin of two members having their adjacent ends pivotally connected together, one member'J of which has its upper end pivotally connected to the inside of-the side-walls d of the bolster while the other member J (which is hinged or pivoted to member J) has its lower end pivotally secured to the bottom of the cradle H in a plane slightly beyond the vertical plane of the pivot from member J. A lateral arm 70 projects from member J throu ha seg-- mental slot K in the adjacent si e wall of the bolster where it is secured to a link I. The opposite end of said link is pivotally connected to a relatively short. arm or crank it rigidly mounted on a rock-shaft (1 whose ends are journaled in suitable hearings in the car end-sills C and which is rocked by means of a liand-lever b on the extended end thereof. a

removed-while the upper end of the lower toggle member J is secured to the former pivotal lug of the upper member, substantially as shown in Fig. 6 ofthe drawings.
